Idaho Statute of Limitations: Filing Deadlines by Case Type

Idaho sets a 2-year deadline for personal injury lawsuits under Idaho Code 5-219, a 5-year deadline for written contract claims under Idaho Code 5-216, and a 4-year deadline for oral contracts. Most felonies must be charged within 5 years, while misdemeanors carry a 1-year limit.

What Is a Statute of Limitations?

A statute of limitations is a law that sets a strict deadline for filing a legal claim or criminal charge. Once the deadline passes, the right to bring that case is permanently lost. Idaho sets different deadlines depending on the type of case and whether it is civil or criminal.

In civil cases, the clock typically starts on the date of the injury or incident. In some situations, Idaho applies a "discovery rule" that delays the start of the clock until the injured person knew or should have known about the harm.

In criminal cases, the clock starts on the date the crime was committed. Certain serious offenses carry no time limit at all, meaning prosecutors can file charges at any point.

Idaho Civil Statute of Limitations

Idaho law sets specific filing deadlines for different types of civil lawsuits. These deadlines are found primarily in Title 5, Chapter 2 of the Idaho Code. If you miss the deadline, the defendant can file a motion to dismiss, and the court will almost certainly grant it.

Personal Injury and Tort Claims

Idaho Code 5-219 groups several claim types under a single two-year deadline. Personal injury claims, wrongful death actions, and all forms of professional malpractice must be filed within two years from the date the cause of action accrued.

For wrongful death cases, the two-year period begins on the date of the person's death, not the date of the act that caused the death.

For medical malpractice, Idaho applies a special discovery rule. If a healthcare provider left a foreign object inside a patient's body, or if the provider fraudulently concealed the malpractice, the deadline does not begin until the patient discovers (or reasonably should have discovered) the injury.

Property and Trespass Claims

Idaho Code 5-218 covers property damage, trespass, and fraud claims. All of these carry a three-year deadline.

For fraud claims, Idaho uses a discovery rule. The three-year clock does not start until the injured party discovers (or reasonably should have discovered) the facts that make up the fraud.

Property damage claims include actions for "taking, detaining, or injuring any goods or chattels." This covers vehicle damage from accidents, destruction of personal belongings, and similar claims.

Contract Claims

Idaho draws a clear line between written and oral contracts. If you have a written agreement, you have five years to file a breach of contract lawsuit. For agreements made verbally without a written document, the deadline is four years.

The difference exists because written contracts provide clearer evidence of the agreement's terms, while oral agreements become harder to prove as time passes.

Judgments and Other Civil Actions

A court judgment in Idaho remains enforceable for 11 years from the date it was entered. After that period, the judgment holder loses the right to collect.

For claims related to the design, construction, or improvement of real property, a special rule applies under Idaho Code 5-241. Tort actions must be brought within the standard limitation period, but that period cannot begin to run later than six years after the final completion of construction.

Claims Against Government Entities

If your claim is against an Idaho state or local government entity, you face a much shorter initial deadline. Under the Idaho Tort Claims Act (Idaho Code 6-906), you must file a tort claim notice within 180 days from the date the claim arose or was reasonably discovered.

This 180-day notice is a mandatory first step. You cannot skip it and go directly to filing a lawsuit. Failing to meet this deadline will bar your claim regardless of how much time remains under the regular statute of limitations.

Child Abuse Cases

Idaho provides extended deadlines for civil tort claims arising from child abuse. Under Idaho Code 6-1704, a victim of childhood abuse must file a civil lawsuit within five years of turning 18, or within five years of discovering (or reasonably should have discovered) the abuse and its connection to the injury, whichever is later.

The victim does not need to identify which specific act in a pattern of ongoing abuse caused the injury. The discovery date can be measured from the last act by the same person that was part of the same scheme.

Tolling Rules: When the Clock Pauses

Idaho law recognizes certain situations where the statute of limitations clock temporarily stops running. These are called "tolling" provisions.

Minors

Under Idaho Code 5-230, if the injured person is under 18 at the time the cause of action arises, the statute of limitations does not begin running until they reach the age of majority (18). However, this tolling cannot extend the deadline by more than six years total.

For example, if a 15-year-old suffers a personal injury, the two-year clock would not start until they turn 18, giving them until age 20 to file. But a child injured at age 5 would not get the full 13 years of tolling. The six-year cap means the deadline arrives sooner.

Mental Incapacity

The same section (Idaho Code 5-230) also tolls the statute of limitations for individuals who are mentally incapacitated at the time the cause of action accrues. The same six-year maximum tolling period applies.

Defendant Absent from State

If the person you need to sue leaves Idaho, the time they spend out of state may not count toward the statute of limitations. Under Idaho Code 5-229, the clock pauses while the defendant is absent from the state and resumes when they return. The same six-year cap on tolling applies here as well.

Discovery Rule

Idaho courts apply the discovery rule in cases involving fraud, medical malpractice with concealment, and other latent injuries. Under this rule, the statute of limitations does not start running until the injured person knew or reasonably should have known about the injury and its cause.

The discovery rule is written directly into certain statutes. Fraud claims under Idaho Code 5-218(4) explicitly state that the cause of action accrues at the time of discovery. Medical malpractice claims under Idaho Code 5-219 include a similar provision for foreign objects left in the body or fraudulent concealment.

Idaho Criminal Statute of Limitations

Idaho's criminal statute of limitations determines how long prosecutors have to file charges after a crime is committed. These deadlines are found in Title 19, Chapter 4 of the Idaho Code.

Crimes With No Statute of Limitations

Under Idaho Code 19-401, the following crimes can be prosecuted at any time, no matter how many years have passed:

• Murder
• Voluntary manslaughter
• Rape (as defined in Idaho Code 18-6101(3) through (10))
• Sexual abuse of a child, lewd conduct with a child, or aggravated lewd conduct with a child (Idaho Code 18-1506, 18-1508, 18-1508B, 18-1508C)
• Producing or making sexually exploitative material (Idaho Code 18-1507(2)(b))
• Acts of terrorism (Idaho Code 18-8102, 18-8103, 18-3322, 18-3323, 18-3324)

Idaho legislators removed the statute of limitations for these crimes because of their severity and the lasting harm they cause to victims and communities.

Felonies

Under Idaho Code 19-402, a prosecution for most felonies must begin within five years of the crime being committed. The prosecution begins with the filing of a complaint or the finding of an indictment.

One notable exception involves ritualized abuse of a child under Idaho Code 18-1506A and 18-1506B. For these offenses, the prosecution must begin within three years after the victim first discloses the abuse to law enforcement.

Misdemeanors

Under Idaho Code 19-403, prosecutors must file charges for misdemeanor offenses within one year of the crime being committed. This applies to all misdemeanors in Idaho.

Criminal Tolling: Absence from State

Under Idaho Code 19-404, if the defendant is out of the state when the crime is committed, the statute of limitations does not begin running until the defendant enters Idaho. Additionally, any time the defendant spends outside of Idaho does not count toward the limitation period. The clock effectively pauses while the defendant is not an inhabitant or usual resident of the state.

Practical Tips for Meeting Idaho Filing Deadlines

Understanding the deadlines is only the first step. Here are some practical considerations:

Keep records of key dates. Write down the exact date of the incident, when you discovered the injury, and any communications with the other party. These dates determine when your clock started.

Do not wait until the last day. Courts have dismissed cases filed even one day late. Give yourself a buffer of several weeks to account for unexpected delays.

Check for shorter government deadlines. If your claim involves a city, county, or state agency, remember the 180-day tort claim notice requirement under Idaho Code 6-906. Missing this step is a common and costly mistake.

Consult an attorney early. An Idaho attorney can help you identify which statute of limitations applies to your specific situation, especially when multiple claims or tolling provisions may be involved.

Watch for tolling events. If you or the defendant were out of state, or if you were a minor at the time of the incident, the deadline may be different from the standard period.
